TREATIVIENT OF WIRE RODS- Specification of Letters Patent.

Patented May 28, 190'#J .Application filed June 6, 1904. Serial No.211,307.

To @ZZ whom it may concern:

Be it known that I, FRED H. DANIELs, a citizen of the United States,residing at Worcester, county of Worcester, State 0f Massachusetts, haveinvented certain new and useful Improvements in the Treatment of WireRods; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

My invention relates to the manufacture of wire rods and moreparticularly consists in improved means for gradually cooling the sameand preventing the formation of scale thereon as they come from thefinishing mill. The Wire rods, as they come hot from said mill, arecoiled or reeled, and, in order to prevent too heavy scale forming whilethe coil is cooling in the open air, it has heretofore been the customin some cases, to cool said rods by immersing them in water immediatelyafter the coiling operation. It has been found, however, that owing tothe highly heated condition of the rods, their immersion at once into abody of water affects them injuriously by chilling and hardening them,and the present invention has been designed with a view to cooling therods less suddenly, by creating around them as they kare coiled, anatmosphere which will be practically non-oxidizing.

In United States Patent No. 737,361, granted to me August 25, 1903, Ishowed, described and claimed an apparatus for cooling the rods duringthe coiling operation and thereafter, by inclosing the coils in apractically air-tight casing, containing steam or a non-oxidizing gasand passing the completed coils slowly through a continuation of saidcasing from lwhich they were finally delivered into a water bath. Thisapparatus effectively prevents the formation of a coating of oXid ofiron upon the rods, and the object of the present invention is to effectthe same general purpose, without inclosing the apparatus in acasing,though a casing may be employed therewith if desired.

In a companion application of even date herewith, Serial No. 211,306, Ihave shown and described an apparatus for accomplishing the same result,in which a revoluble coiler arm is employed to coil the wire, and wherethe reel and the coil are stationary. A plurality of stationaryatomizers are arranged above the reel to spray a finely divided mistonto the wire as it is coiled, and said coiler arm being constructed tofeed a stream of Water with the wire, the revolution of the arm throwsthe fine stream of water violently against the reel, the pins, and allparts of the coiling apparatus adjacent to the place where the coilingis carried on.

The subject matter of my present invention comprises an apparatusdesigned to obtain the same general result, but in this invention thereel itself is rotated and preferably a single stationary atomizer isemployed for spraying the coil. As there is the same relative movementbetween the atomizer, and the water pipe as in the companion invention,the same breaking up and fractional distribution of the water iseffected here, but it is believed that the present apparatus producesbetter and quicker results, owing, among other things, to the fact thatthe projection ofa stationary spray upon a positively moving surfaceappears to break up or subdivide and distribute the water morethoroughly and effectively than when the spray moves and the parts ontowhich itis projected are stationary.

The details of this apparatus in its preferred form, its operation andthe advantages obtained by its use will all be clearly set forth. in thefollowing description and claims taken in connection with theaccompanying two sheets of drawings. I would have it understood,however, that certain of my claims herein are designed to cover theapparatus of either and both applications. Some of the claims herein arelimited to the apparatus illustrated and described in this application,but other claims are intended to more broadly express the invention so'as to cover the apparatus illustrated and described inapplication211,306, as well as the apparatus of this case.

In the accompanying drawings, Figure 1 is a side elevation partly insection, of a reeling plant constructed according to my presentinvention; Fig. 2 is an end view of the same partly in section and Fig.3 is a central, vertical section, on a larger scale, of one of the reelsand spraying nozzles.

Referring to said figures, Z represents a tank or reservoir for waterand i a reservoir for compressed air or other gaseous fluid. A pipe gleading from the former communicates with spraying nozzles or atomizersh. A

pipe leading from the latter communicates with nozzles k axially locatedin said atomizers. The pressure in said pipes j may be controlled, as isthe case in my said companion application, by needle valves adapted tobe manually controlled, as by the means indicated at k.

The pipes for guiding the wires as they come from the finishing mill areindicated at f, and with them communicate branch pipes e, provided withcocks e, by which a stream of water can be fed through each of saidpipes f with the wire, all as described in said appli` cation.

As each coiling and cooling mechanism is an exact duplicate of theother, l will describe the construction of one only.

The wire, as it comes from the pipe f, is fed to the coiling mechanism,which in this case is the reel, itself, comprising the rotary base battached to and driven by the shaft b and carrying the pins or pegs c.To the shaft b is attached the hub n of the base plate l), and said hubis supported on an annular bearing o. The shaft b is hollow and has arod d extending through it, to the upper end of which is attached thehub carrying the coil supporting plate or grid d which is slotted as ate for the passage of the pins c, and which is pushed up in a well knownmanner to raise the coil above the pins when it has been completed andis ready to be discharged.

The atomizer h has an inverted cone 7i at its open end so that only anarrow adjustable annular aperture is left for the egress of the water,which, owing to the conical shape of the passage leading to saidaperture; is sprayed onto the coil in the form of a hollow cone, as willbe apparent from an inspection of Fig. 3, and is delivered in the formof a ringv or circle approximating that of the coil.

'The entire coiling mechanism is contained within a casing a providedwith an aperture for the pipe f and with a drain pipe afor the water.

Vhen the coil is completed, the rod d is raised by any suitable means,not shown, and lifts, by means of the plate or grid d, the coil abovethe upper ends of the pins e, and the coil is then removed from saidplate onto a conveyer p, or other suitable supporting surface, such aconveyer and its support p being diagrammatically represented in -Figs.l and 2, and which may run in a tank of water for finally cooling thecoil, if preferred.

The operation will now be described.

The wire coming from the rolls g of the finishing mill, is guided intothe pipe f and issuing therefrom is engaged by the pins c of therevolving reel. As soon as a sufficient number of turns ahve been madeto cause the necessary frictional engagement of the wire with the pins,the cock e is opened and a stream of water is fed into said pipe alongwith the wire. This stream strikes the revolving coil and the base andpins of the coiler and also strikes the conical spray coming from thenozzle 7a,v and mingles therewith, and owing to their impact togetherand to their striking the revolving base I) of the coiler and the grid eand pins c, and other` moving parts adjacent to the coil, the water isdelivered onto the hot coil in. a .linely divided state, the resultbeing the formation of an atmosphere of steam and mist, which graduallycools the coil while preventing the formation of oxid, as described in.my said companion application.

So far as l know, I am the first to project water in the form of afinely divided spray onto a moving surface in a wire rod ceilingapparatus, whether said moving part be the coil itself or some plate orpart of the coiler proper. l do not, therefore, desire or intend to belimited to any particular part as the moving surface, nor to anylocation or construction of said moving` part. Neither do l desire orintend to limit myself to any particular source of the water, nor to anylocation of the pipe or nozzle whence it issues, nor to any directionfor the projected stream or spray.

As shown herein, the surface onto which the spray is thrown is formedpartly of the eoil and partly of the bottom plate b and the coil raisinggrid e, and it is to be noted that, (as indicated by the lines in Fig.3,) part ol the spray is projected directly onto some parts of the coil,and part is delleeted or rebounds from the base l) onto other parts ol'the coil, this arrangement serving in a high degree to efl'ect suchcomplete braking up of the line strrams or spray, that the formation ofan atmosphere of steam around the coil and the entire apparatus iseffectually quickened and easily maintained.

Any moving plate or part, whether a necessary part of the ceilingapparatus, or a special part provided for the purpose, would be withinthe scope of the invention, asl believe myself entitled to cover broadlyany apparatus involving any arrangement for providing` a moving baffleplate or surface onto or against which the spray is projected and fromwhich it is dellected or rebounds so as to be further broken up.
